Action and working conditions of cylinder head of marine diesel engine parts

DK28 diesel engine accessories effect

(1) Composing the combustion chamber

(2) Install accessories such as fuel injectors, intake and exhaust valves, start valves, indicator valves, safety valves, etc.

(3) Constitute cooling water channels and intake and exhaust channels

L28/32 diesel engine accessories Working condition

(1) Withstand the pre-tightening force of bolts.

(2) Withstand the action of gas force: compressive stress on the contact surface and tensile stress on the cooling surface.

(3) The role of thermal load: compressive thermal stress on the contact surface, and tensile thermal stress on the cooling surface.

(4) Bearing corrosion fatigue effect: The cylinder head withstands the corrosion of cooling water and mechanical cyclic stress, causing corrosion fatigue.
